FLOOR-LIFTING DEVICE.

To all whom it may concern:

Be it known that I, RoY WV. WILLIAMS, a citizen of the United States, residing at Utica, in the county of Yankton and State of South Dakota, have invented certain new and useful Improvements in F loor-Lifting Devices, of which the following is a specifiing surface 2 of the head 1 is engaged with cation. 1 This invention relates to improvements in tools and it is the principal object of the invention to provide a novel form of tool for removing flooring from oists and the like in building in a rapid and effectual manner and with but little effort upon part of a user.

Other objects will be in part obvious andin part pointed out hereinafter.

In the more detailed description of the invention which is to follow, reference is made to the accompanying drawings, but it will be understood that only one form of the invention isillustrated therein and that various changes and modifications can be made without departing from the spirit or scope of the invention, as defined in the claim.

In these drawings:

Figure 1 is a fragmentary perspective of the improved tool, and

Fig. 2 is a vertical longitudinal section therethrough. v

Referring now more specifically to the d rawings, in connection with which like ref erence characters will designate correspond the boards to be started from the joists with the least possible effort upon part of a user. In this connection, it is to be noted that the circular shaped bearing Qwith serrations 3 are arranged adjacent the rear ends of the arms 4 and extend therebetween, to provide a rounded fulcrum for the rolling action of the tool, the serrations serving to provide means for preventing the slipping of the tool Wl'lGILlIl use, that is, when the curved beara joist and the arms 4 straddle the same.

Specification of Letters Patent. Patented 1111915, 1920, Application filed June 15, 1918. Serial No. 240,125.

I .An extension 6 is formed on the opposit-e end of the head 1 and is provided with a tapered socket for receiving the complementally shaped end of a suitable form of handle 7, which handle, as will be understood, can be of any desired length, such as conditions or preference may dictate.

In using the improved tool, the arms 4 straddle the joist of the flooring and the rounded bearing 2 thereof engages the marginal portion of the same. Hence, when the tool is rocked, the arms at will be moved upwardly into engagement with the underside of the board. As will be noted, the curved intermediate portions of the arms 4 will first I marginal portion of the joist and said tool.

It of course will be understood that various forms of handlescan be substituted for the I oneshown, as may be desired.

As indicated, I do not wish to be understood as confining the invention to the particular embodiment chosen for illustration herein, nor to. the exact construction, ar-

rangement and adaptation of parts shown and described, but I reserve the right to make any changes and alterations as fairly fall within the spirit and scope of the invention.

A lifting tool comprising an enlarged head substantiallycircular in cross sectional con figuration, a soeketed shank formed on the head, longitudinally disposed medially enlarged spaced parallel arms formed integrally with and extending from the head,

the curved surface of the head between and beneath the arms being serrated to provide a gripping portion, andthe curved surface of the head above the arms being unbroken to provide an abutment for an object acted upon.

In testimony whereof, I afiix my signature hereto.

ROY .w. WILLIAMS. I
